1 Overview
Hu et al. in prep. Protistan grazing and biogeography at Gorda Ridge hydrothermal vent field
Code for all data analysis and figure generation, including grazing experiment analysis and sequence data processing. * Import raw counts from FLP disappearance experiments * Perform calculations to estimate grazing pressure * Generate figures to visualize grazing pressure * Import and quality control 18S and 16S tag-sequencing data * Taxonomy curation * Statistical analyses * Figure generation
2 Set up working R environment
The following analysis was performed in R version 3.6.1. All input files are available on the Gorda Ridge GitHub.

Counts from Vent sample 110 T0 control were repeated three times (3 separate slides). Results are used below as technical replicates to estimate the percentage error rate.
By determining error rate from microscopy counting we can be more confident in evaluating true differences in values.

# sample 3 times (3 different days); this was counted separately to to estimate a
# personal error rate This is the % max and min that we will consider to be a

Here we are curating the 16S taxonomy assignments so we can get an informative look at the in situ bacteria population diversity and biogeography. Places ASVs below a user designated THRESHOLD into the “Other” category - ASVs that make up < X% of the total data set. For this work, a threshold of 0.1% was used. The other curation of taxonomic assignment was to highlight those groups known to inhabit the region or other chemosynthetic habitats.

Use these ASVs downstream to explore hypotheses with correlation results. Below set up 16S and 18S rRNA gene output data as phyloseq objects to import into SPIEC-EASI. Following SPIEC-EASI analysis, export as dataframe, add metadata, and process.
